Answer:
The addition of sulfate ions shifts equilibrium to the left.
Explanation:
Hello!
In this case, according to the following ionization of strontium sulfate:
[tex]SrSO_3(s)\rightleftharpoons Sr^{2+}+SO_4^{2-}[/tex]
It is evidenced that when sodium sulfate is added, sulfate, [tex]SO_4^{2+}[/tex] is actually added in to the solution, which causes the equilibrium to shift leftwards according to the Le Ch athelier's principle. Thus, the answer in this case would be:
The addition of sulfate ions shifts equilibrium to the left.

Explanation:
Emma draws another diagram showing how adding energy affects this wave. How does her new diagram compare to this diagram?
A
Her diagram shows higher wavelengths.
B
Her diagram shows lower wave amplitudes.
С
Her diagram shows lower wave frequencies.
D
Her diagram shows higher wave amplitudes.
Answer:
I would say it’s either B or D
Explanation:
I don’t know if it’s asking about her current diagram
In the electromagnetic spectrum,adding energy to the wave will give higher wave amplitude as energy and amplitude are directly proportional.
What is electromagnetic spectrum?The electromagnetic spectrum consists of electromagnetic radiation consisting of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.
The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.
In vacuum ,all the electromagnetic waves travel at the same speed that is with the speed of air.The position of an electromagnetic wave in an electromagnetic spectrum is characterized by it's frequency or wavelength.They are emitted by electrically charged particles which undergo acceleration and subsequently interact with other charged particles.

explain how the density of the crust, mantle, and core are related
to the position of these layers.
Brainlest will get 100 points
Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth’s mass. Finally, the core is mostly iron metal. The core makes up about 31% of the Earth. Lithosphere and asthenosphere are divisions based on mechanical properties. The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid. The asthenosphere is partially molten upper mantle material that behaves plastically and can flow. This animation by Earthquide shows the layers by composition and by mechanical properties.
define saturated and unsaturated fats
Answer:
A saturated fat is a type of fat in which the fatty acid chains have all or predominantly single bonds. A fat is made of two kinds of smaller molecules: glycerol and fatty acids. Fats are made of long chains of carbon atoms. Some carbon atoms are linked by single bonds and others are linked by double bonds and a type of fat containing a high proportion of fatty acid molecules with at least one double bond, considered to be healthier in the diet than saturated fat.

What is the energy of a TV wave that NBC broadcasts, if it has a wavelength of 32 meters?
Answer:
Explanation:
E = hc/λ
h = planck's constant = 6.66 x 10 ^ -34
c = speed of light = 2.98 *10^8 m/s
E = (6.66 x 10 ^ -34 )(2.98 *10^8)/32
= 19.85 * 10 ^-26
=0.62 x 10^-26
= 6.2 x 10^-27 J
You are given 68 g of aluminum (Al) and excess water. How many grams of aluminum oxide (Al2O3) can you make?
4 Al + 3O2 --> 2Al2O3
Question 13 options:
95.84 g Al2O3
2.52 g Al2O3
128.48 g Al2O3
101.96 g Al2O3
When 6.8776g of aluminium reacts with an excess of oxygen, 6.8776g of aluminium oxide are produced.
What is the name of aluminum oxide?
Al2O3 is an inorganic chemical reagent with the chemical name aluminum oxide. Other names for it include alumina, alundum, al-alumina, and aloxide.
If there are 4 moles of Al that equals 107.926156 grams of 4Al
If there are 2 moles of Al2O3 that equals 203.9226g
If 107.9261 grams of 4Al equals 203.9226 grams of 2Al2O3 then, 3.64g of Al equals x
107.9261 / 3.64 = 203.9226 / x
(107.9261) x = (203.9226) 3.64
107.9261 x = 742.2782
dividing both LHS and RHS by 107.9261,
107.9261/107.9261x = 742.2782/107.9261
x = 6.8776g
Hence, 6.8776g of aluminium oxide are produced.

water is a ____ molecule meaning the positive hydrogen end attracts the negative oxygen ends of another
A. balance
B.universal
C. wet
D.polar
please answer! will give brainliest
Water is a polar molecule where, the positive hydrogen end attracts the negative oxygen ends of another water molecule. Thus, option D is correct.
What is polarity ?Polarity is ability of charge separation in a molecule. In some molecules, the positive and negative ends exists separately and both ends remains reactive towards the counter charged end of other molecule.
The charge separation in molecules results in a dipole moment. Permanent dipole moment make the molecule polar. Water is a polar molecule.
The shared pair of electrons in water are more attracted towards the electronegative oxygen atom leads the charge separation. This polarity helps to the formation of strong intermolecular hydrogen bonding.

if the pressure, volume, and tempature of a gas are known which can most likely be found by using the ideal gas law
• the molar amount of the gas
•the partial pressure of the gas
•the stand temperature
•the molar mass
Answer:
• The molar amount of the gas
Explanation:
Hello!
In this case, according to the ideal gas law:
[tex]PV=nRT[/tex]
Whereas P stands for pressure, V for volume, n for the molar amount of the gas, R for the universal gas constant and T for the temperature, we can see that as pressure, volume and temperature are given, we can compute the molar amount of the gas as shown below:
[tex]n=\frac{PV}{RT}[/tex]
Since R is a constant always.

Which would have a stronger attraction to the nucleus, the outer electrons of a carbon atom or the outer electrons of an oxygen atom? Why?
The outer electron of an oxygen atom will have a stronger attraction to the nucleus than the outer electrons of a carbon atom.
In the periodic table, atomic sizes decrease across the period. This decrease in atomic size stems from increase in the size of the nuclear charge.
This implies that as we move from left to right in the periodic table, atoms of elements become smaller due to stronger nuclear attraction as the size of the nuclear charge becomes larger.
Oxygen atom has a nuclear charge of +8 while carbon atom has a nuclear charge of +6. Therefore, outer electron of an oxygen atom will have a stronger attraction to the nucleus than the outer electrons of a carbon atom.
